My Dynam Hawk Sky power plant upgrade>>>>>>>>

I recently have had very bad luck with my dynam hawk sky as you can see by the amount of gorilla glue and duct tape. So far I have sliced the wing off by running into a field goal post at a football field, hit trees twice, and ran it full speed onto the top of the roof of my local high school...but glue and tape can solve anything :)...with the extra weight from the tape and the glue I decided to upgrade to two 400 speed microjet v3 motors and 2 20amp ESC's to power this beast. I hot glued the wooden adapter to the wings and it holds up just fine. I also am going to be running 3 blade 6 by 4 props to get a clean crisp sound. Tomorrow I will testing this setup and I hope it works out well

  • @Steve. I have all of the equipment and hardware and software for AP flight and I have had it up and running with simulations. But I'm still a little reluctant to put all the expensive electronics in the plane when I'm still crashing pretty frequently. It doesn't help that I live on the coast of washington state..which equals tons of wind and rain...all the time. I am still using the old arduPilot regular board and imu.
  • I've got the exact same plane, and I must say those cracks around the cockpit look pretty familiar ;-)

    It's good to see that it'll still fly after a considerable amount of.. modification. I also wanted to ask you, did you ever plan on installing an AP in your Dynam?
  • I just flew it about an hour ago...and holy crap....it accelerates like a rocket. At only about half throttle I was hitting 200 feet in about 5 seconds. Most of the flying was around quarter stick. I didn't notice too much pull in either direction but there was alot of wind with gusts. I made a little bit of a crash landing and broke a prop. But other than that, the flight was pretty successful with this power arrangement. I ordered a 8 by 4 by 3 prop and a counter rotating prop to match it. We'll see how that goes once they arrive. I think it's going to have a nice clean sound.

    The pull will change depending on how much throttle you apply, but you might be able to mix it out with a throttle -> aileron mix.
  • Is the pull going to be bad enough to where I can't fly it at all? Or should I be ok?

    Your original instructions should show the proper CG. But 2" back sounds about right. You do indeed want a counter rotating prop. Just get a pusher for the same size as your puller and that should do it.
  • @Chris.... My CG is about 2 inches back from the front of the wing. I am assuming that the CG is supposed to be somewhere around there? But honestly, I have no idea where it is supposed to be :)

    And one more question. Should I get counter rotating props because if I don't , the plane will want to pull to one side? If so, where is a good place to buy counter rotating props?

    I take it you feel the need...the need for speed?? I think all that foam is weighing you down!

    Keep flying

    Wow. Just wow. How's your CG?
